Diagnostic Services

Tandem Veterinary Clinic in Somerville provides comprehensive in-house diagnostic services including full laboratory capabilities, digital radiography (x-ray), wellness bloodwork panels ($304-$403), and fecal testing ($120-$175). Our experienced veterinary team uses advanced diagnostic equipment on-site to deliver same-day results, enabling accurate diagnoses and faster treatment decisions. With the ability to perform complete blood counts, chemistry panels, urinalysis, parasite screening, and digital imaging without sending samples to outside labs, we minimize wait times and reduce the stress of multiple visits for your pet.

All pets benefit from routine diagnostic screening. Annual wellness testing is recommended for healthy adult pets (1-7 years), while senior pets (7+ years), breeds predisposed to specific diseases, and pets with chronic conditions need more frequent monitoring. Diagnostic services are essential for sick or injured pets showing symptoms, pre-surgical screening, medication monitoring, and emergency situations. Indoor and outdoor pets alike require regular fecal testing for parasite detection.

Veterinary diagnostic services encompass laboratory testing and imaging technologies that allow veterinarians to see inside your pet's body and analyze bodily fluids to identify diseases, injuries, and abnormalities. These services form the foundation of modern veterinary medicine, transforming veterinary care from relying solely on physical examination to evidence-based diagnosis using objective data.

In-house diagnostic capabilities mean tests are performed at the veterinary clinic rather than sent to outside laboratories. This includes clinical chemistry analyzers for bloodwork, microscopes for cytology and fecal analysis, urinalysis equipment, and digital x-ray machines. Having these technologies on-site dramatically reduces the time between sample collection and diagnosis, often providing results within the same appointment rather than requiring days of waiting.

The three core diagnostic modalities are hematology (blood cell analysis), clinical chemistry (organ function and metabolic testing), and diagnostic imaging (x-rays, ultrasound). Together, these tools allow veterinarians to evaluate organ function, detect infections, identify structural abnormalities, screen for parasites, and monitor chronic disease progression—often detecting problems before pets show outward symptoms.

A Complete Blood Count (CBC) analyzes red blood cells, white blood cells, and platelets to detect anemia, infections, immune system disorders, clotting problems, and some cancers. Blood chemistry panels evaluate kidney function, liver enzymes, blood sugar, electrolytes, and proteins—providing a comprehensive snapshot of metabolic health and organ performance. These tests are essential for pre-anesthetic screening, diagnosing illness, and monitoring chronic conditions like kidney disease or diabetes.

Fecal examination identifies intestinal parasites including roundworms, hookworms, whipworms, tapeworms, giardia, and coccidia. Because many parasites don't cause visible symptoms until infestations become severe, annual fecal testing is a critical preventive measure. Some intestinal parasites are zoonotic, meaning they can transmit to humans, making regular screening important for family health as well as pet health.

Digital radiography (x-ray) visualizes bones, organs, and some soft tissues to diagnose fractures, arthritis, tumors, heart enlargement, pneumonia, bladder stones, foreign body ingestion, and pregnancy. Unlike traditional film x-rays, digital x-rays produce immediate images with superior detail and can be digitally enhanced to highlight specific structures. This technology has revolutionized emergency veterinary care by enabling rapid diagnosis of life-threatening conditions like gastric dilatation-volvulus (bloat) or internal injuries from trauma.

Wellness diagnostic testing in apparently healthy pets is one of the most powerful tools in preventive veterinary medicine. Many serious diseases—including kidney disease, diabetes, hyperthyroidism, and early-stage cancer—develop gradually without obvious symptoms until they reach advanced stages. By the time a pet shows clinical signs of kidney disease, for example, up to 75% of kidney function may already be lost. Annual or biannual wellness bloodwork establishes baseline values and detects subtle changes that indicate disease in its earliest, most treatable stages.

Senior pet wellness programs typically recommend comprehensive diagnostics every six months because disease processes accelerate with age. Dogs and cats age approximately seven years for every human year, meaning significant health changes can occur between annual exams. Senior screening panels often include thyroid testing, urinalysis, and extended chemistry profiles to catch age-related conditions early. Studies have shown that early intervention in chronic kidney disease, for instance, can add years of quality life through dietary management and supportive care.

Baseline diagnostic values established when pets are young and healthy become invaluable reference points throughout their lives. An individual pet's normal kidney values or liver enzymes may differ slightly from textbook ranges, so knowing their personal baseline helps veterinarians identify meaningful changes earlier. This personalized approach to diagnostic interpretation is only possible when wellness testing begins early and continues regularly throughout the pet's life.

Most diagnostic procedures are minimally invasive and well-tolerated by pets. Blood draws typically involve a quick venipuncture from the jugular vein, front leg (cephalic), or back leg (saphenous), taking just seconds to collect the sample. Pets may be gently restrained by trained veterinary technicians, but the procedure causes no more than momentary discomfort similar to a human blood draw. Fecal samples are either collected during the visit via rectal thermometer or brought from home in a clean container.

For digital x-rays, pets are positioned on a specialized table with the x-ray plate beneath them. Cooperative pets often require only gentle positioning, while anxious or painful pets may benefit from mild sedation to ensure comfort and image quality. The actual x-ray exposure lasts only a fraction of a second. Most pets experience no discomfort from the x-ray process itself, though positioning may be uncomfortable if injuries are present. Veterinary staff use protective lead aprons and follow strict radiation safety protocols.

Results timelines vary by test complexity, but in-house diagnostics typically provide same-day answers. Bloodwork is usually ready within 30-60 minutes, x-ray images are available immediately, and fecal examinations are completed within an hour. Your veterinarian will review results, explain findings in understandable terms, and discuss any necessary follow-up testing or treatment. Written reports and digital x-ray images can be provided for your records or to share with specialists if needed.
